You should catch exception only if you want to process it in any way:
* log
* convert to another (usually more specific) exception. For example IOException can be converted to some business level exception.
* swallow (in extremely rare case). E.g. exceptions from InputStream.close() methods are often swallowed, because it does not make sense to report any issues for stream closing.
* exception is part of business logic and should be handled separately.
* etc

In your case you DO NOT need to catch exceptions in this method.

If you have hard times understanding exceptions please get familiar with Robust Java: Exception Handling, Testing, and Debugging by Stephen Stelting, specifically first chapter.
